Thatta: History
=== Early ===
Thatta may be the site of ancient Patala, the main port on the Indus in the time of Alexander the Great, though the site of Patala has been subject to much debate. Before it, Hindus called it Sarnee Nagar, but in 332 BC, Greeks first time called it Pattala or Patala then it became Nagar Tatta in Mughal Period. Muhammad bin Qasim captured the region in 711 CE after the defeating the Raja Dahir in a battle north of Thatta. Thatta is reported by some historians to have been the ancient seaport of Debal that was mentioned by the Arab conquerors, though others place the seaport at the site of modern Karachi. At the time of the Umayyad conquests, small semi-nomadic tribes were living in the Sindh region. The Umayyad conquest introduced the religion of Islam into the hitherto mostly Hindu and Buddhist region.
Following Mahmud of Ghazna's invasion of Sindh in the early 11th century, the Ghaznavids installed Abdul Razzaq as Governor of Thatta in 1026. Under the rule of the Ghaznavids the local chieftain Ibn Sumar, then ruler of Multan, seized power in Sindh and founded the Sumra dynasty, which ruled from Thatta from 1051 for the next 300 years. Under Sumra rule, Thatta's Ismaili Shia population was granted special protection. The Sumra dynasty began to decline in power by the 13th century, though Thatta and the Indus Delta remained their last bastions of power until the mid 14th century.
In 1351, the Samma Dynasty, of Rajput descent from Sehwan, seized the city and made it their capital as well. It was during this time that the Makli Necropolis rose to prominence as a funerary site. Muhammad bin Tughluq died in 1351 during a campaign to capture Thatta. Firuz Shah Tughlaq unsuccessfully attempted to subjugate Thatta twice; once in 1361 and again in 1365.
In 1520, the Samma ruler Jam Feroz was defeated by Shah Beg of the Arghun-Tarkhun dynasty, which in turn had been displaced from Afghanistan by the expanding Timurid Empire in Central Asia. The Tarkhuns fell into disarray in the mid-1500s, prompting Muhammad Isa Tarkhun (Mirza Isa Khan I) to seek aid from the Portuguese in 1555. 700 Portuguese soldiers arrived in 28 ships to determine, at the time of their arrival, that Isa Tarkhun had already emerged victorious from the conflict. After the Tarkhuns refused to pay the Portuguese soldiers, the Portuguese plundered the town, robbing its enormous gold treasury, and killing many inhabitants. Despite the 1557 Sack of Thatta, the 16th century Portuguese historian Diogo do Couto described Thatta as one of the richest cities of the Orient.
Nevertheless, some Portuguese presence was early in the 16th century with the conquest of Hormuz by Afonso de Albuquerque in 1507, which started the relationship with Sindi. Later in the first decade of the 16th century, traders created a factory (feitoria), and at the end of the 16th century a religious Order (Carmelitas Descalços) Secular Order of Discalced Carmelites a convent. …
